How this service works
Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.
Output
Returns a JSON object containing the SKU name ('settleattest'), a diagnostic note clarifying it is an example paid shape, the price ('$0.03'), and the title ('Settle Attest'). Unpaid requests receive HTTP 402 with EIP-3009 payment extras instead.
Example use cases
Validate x402 payment integration end-to-end
“I want to verify my x402 payment client actually works — can you hit the settle attest endpoint on OpenX402 and show me the paid JSON response it returns?”
Debug HTTP 402 and EIP-3009 response format
“My app is getting HTTP 402 errors with EIP-3009 extras — can you call the x402 settle attest diagnostic so I can see exactly what an unpaid response looks like versus a paid one?”
Confirm OpenX402 facilitator is live and responding
“Before I build out my x402 integration, can you make a test call to the OpenX402 settle attest endpoint and confirm it's live and returning the right settleattest SKU shape?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/settleattest?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cheap ($0.03 USDC), real-world test of the x402 paid API protocol using the OpenX402 facilitator — especially to verify EIP-3009 payment flows, inspect HTTP 402 error shapes, or confirm that a payment-aware agent client can successfully authorize and receive a paid response. Not suitable for production data needs; purely a diagnostic and integration-testing tool.
Side effects
- HTTP 402 returned if payment via OpenX402 facilitator is missing or invalid, with EIP-3009 authorization extras in the response
- Non-OpenX402 facilitators are rejected — only OpenX402 is accepted
- Malformed payment headers result in 402 without a valid diagnostic payload
- Network or server errors may return 5xx responses with no diagnostic data
